net_version returns the network ID of the chain a node is connected to, given as a plain decimal string. For Ethereum mainnet the answer is "1" — the same value as chain ID 1, since the two coincide on Ethereum even though they are distinct concepts at the protocol level. It is a quick way to confirm you are talking to the right ETH network before you do anything that matters. Point the call at https://ethereum.therpc.io/YOUR_API_KEY and you will get "1" back; a Sepolia endpoint would answer "11155111", Holesky "17000". The method takes no parameters and reads no state.
"1") before broadcasting a transaction that moves real ETH."11155111") or Holesky ("17000") so staging never writes to production state.Este método não aceita parâmetros. Passe um array vazio [].

1), but they are not the same field, and on some networks they diverge. For anything that signs a transaction, use eth_chainId, since EIP-155 replay protection is keyed on the chain ID, not the network ID.0x-prefixed hex you see almost everywhere else in the JSON-RPC API. Parse it as base 10, and do not feed it to a hex decoder expecting "0x1".
